Between their ends the arms are provided with rigid upward extensions 9 connected fixedly together by means of a horizo tal cross bar .10, the arms,

extensions, and c oss bar thus forminga frame or yoke, pivlotally mounted at one end on the pot on a horizontal transverse axis, and carrying atits opposite end the sprueplate, which, by the swinging movement of the yoke, is moved vertically with relation to the pot and mold between the two. It is seen, therefore, that'the sprue-plate is capable of two movements, one horizontally facewise with the melting pot to and from the mold, and the other vertically and edgewise with relation to the pot mouth and mold. By the horizontal movements, the plate is alternately seated against the rear face of the mold and withdrawn therefrom after the casting operation, the retreat of the plate acting to sever the sprue or gate from the slug. By the vertical edge-wise movement of the plate, the gate is carried away from the mold and automatically ejected. 4 v

I propose to effect the vertical movements of the plate automatically by the retreat of v the pot, which automatic action may be effected by providing the arms 7 near their rear ends with depending lugs 11, arranged to 'encounter'fixed fingers 12, mounted on the machine frame and extending in the path oft he lugs, the relation of the parts being such that the lugs will encounter the fingers at. the moment when the rearward movement of the pot is nearly completed, the result being that the yoke carrying the plate will be swung upward on its axis and will correspondingly elevate the plate.

The automatic ejection of the sprue from the sprue-pla-te is effected by means of a' horizontal blade 13, fixed to the front of the pot, with its forward edge so disposed that as the plate is elevated the rear face of the latter will move in proximity to the edge of the blade, the result being that the projectin portions of thesprue, left by the withdrawal of the pot mouth from the sprueplate as the pot starts to retreat, will be :moved against the edge of the blade, and the plate continuing its upward movement, the sprue will be islodged and drawn out of the plate, the engagement of the edge of the plate with the pro ections on the sprue, acting to loosen the .latter and causing it to be wlthdrawn in a downward direction as the trated in Fig. 2.

In the operation of the mechanism described, the parts being in the position past the blade, as illus-- shown in Fig. 2, with the melting pot in retracted position, the sprue-plate elevated {closing the mold, the pot begins'its forward movement, the studs moving forward in the slots, and thereby disengaging the lugs from the fingers and permitting the yoke to fall,

which will lower the sprue-plate infront of the pot mouth. 'As the forward movement of the pot continues, the sprue-plate will be carried against the rear face of the mold, and the pot mouth seated against the rear face of the plate, after which the parts'willcome to rest in the position for casting shown in Fig. 1. The pot plunger being operated,a quantity of molten metal is injected from the mouth through the sprue-plate and filling the mold and sp'rue-plate will form a slug with a gate or sprue attached to its base along a central line.. The casting .operation being now completed, the pot begins its retreat, the first portion of its movement being relatively to the sprue-plate, which relative motion takes place as the studs 8 move rearwardly in the slots in the arms, and without disturbing the position of the plate, but resulting in the separationof the pot mouth from the rear face of the plate,

thereby leaving a number of projections on the rear edge of the sprue formed by the holes in the pot mouth.' As the studs, in the continued movement of the pot, encounter the rear ends of the slots, the sprueplate will be drawn horizontally and ata' slight upward inclination from the mold, thereby severing the thln connecting web between the gate and base of the slug, the

latter being retained in the mold by the.

usual shoulders at the ends of the same. The further movement of the pot rearward,

carries the lugs 11 into engagement with fingers 12, whereby the yoke will be rocked and the sprue-plate carried upward past the ejecting, blade 13, which being encountered by the projections on the rear edge of the sprue, the latter will be dislodged and drawn from the plate.
